LIQUID-GOATING MACHINE.

Application filed July 21, 1909.

To all whom it may concern:

Be it known that I, REME A. BEAUSEJOUR, a subject of the Crown of Great Britain, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Liquid- Coating Machines, of which the following is aspeciflcation.

This invention relates to that type of liquid coating machines in which the articles to be treated to a liquid coating are held in an article holder and raised and lowered by fluid actuated means; and it has particularly to do with the mechanism for raisin and lowering the article holder and for steadying the same in its vertical move ment.

One object is to provide fluid actuated means for raising the article holder, which means is adapted to be operated by the gravitational force of liquid flowing from a relatively elevated source, without the necessity of utilizing force pumps.

Another object is to provide new and improved mechanisms for rendering the vertical movement of the article holder absolutely even and steady.

lVith these objects in view, I provide a plurality of cylinders and fluid actuated pistons for raising and lowering the article holder, and I further provide a flexible connection between the pistons for causing them to cooperate in strict uniformi y in raising the holder, and -a flexible connection between various parts of the lifting bracket, which flexible connection passes over certain fixed supports, as will be hereinafter more fully described.

A practical embodiment of my invention is represented in the accompanying drawings, in Which- Figure 1 represents a view in side elevation, partially in section, of an embodiment of my invention, the bracket and lifting mechanism being shown in their lowered po sitions in full lines and in their raised positions in dotted lines, and Fig. 2 is a top plan view of the same.

The dipping tank is denoted by 1 and it is provided with a flange :2 for supporting it on the floor or other support 3. The cylinder 4 of a fluid actuated device is located adjacent to the tank 1, and is provided with a collar 5 for supporting it upon the plate 6. The lower end of the cylinder may also rest Specification of Letters Patent.

- the cylinder 4.

upon a support 7. A piston 8 is fitted to reciprocate within the cylinder 4, and its rod 9 extends upwardly through the top of the cylinder.

The fluid inlet pipe is indicated by 10 and it has a pressure regulator 11 and a pressure regulator gage 12 therein. This inlet pipe 10 is provided with a branch pipe 13 leading to the upper end of the cylinder 4 and another branch pipe 14 leading to the lower end of said cylinder.

The fluid outlet pipe 15 is connected to the branch pipe 13 through a pipe 16 having a manually operated valve 17 therein. This outlet pipe 15 is also connected to the branch pipe 14 through a pipe 18 having a manually operated valve 19 therein. 1-1 manually operated valve 20is located in the branch inlet pipe 14, and a manually operated valve 21 is located in the inlet pipe 10.

The cylinder :22 of a second fluid actuated device is supported by the collar 23 on the plate 6 adjacent to the cylinder 4 of the firstmentioned fluid actuated device. A piston is fitted to reciprocate "within the cylinder 22 and its rod 25 extends upwardly through the top of the said cylinder. This cylinder 22 is provided 'with a fluid inlet pipe 26 having a manually operated valve 27 therein and with a fluid outlet pipe 28 having a manually operated valve 29 therein. The fluid inlet pipe 26 of the cylinder 22 is connected to the fluid inlet pipe 14 oi A bracket is carried by the piston rod 9 above the cylinder 4, which bracketcomprises a tubular post 30 surrounding the piston rod 9 and having a horizontal arm 31 projecting from its lower end; and a diagonally arranged supporting strap 32 extending from its upper end to the horizontal arm 31 at a point between the inner and outer ends of the said arm. A vertical post 33 is arranged adjacent to the cylinder 4, which post is of suflicient height to extend above the top of the bracket when the latter is in its raised position. The top of the post is rigidly secured to an upper support 34, and its bottom rests on the plate 6. The upper end of the piston rod 25 is provided with a pulley 35 while a double pulley 36 is mounted in the fixed support 34.

The piston rods 9 and 25 of the fluid actuated devices are interconnected by means of the flexible connection 37, one end of which is attached to a loop 38 at the upper end lit) of the piston rod 9 and the other end of which is attached to the fixed support 39, while the said flexible connection passes over the pulley 3G and under the pulley 35. By reason of the fact that the pulley 35, mounted on the upper end of the piston rod 25, is supported in a bight of the flexible connection 37, while the piston rod 9 is attached to one end of the said flexible connectlon, the piston 24 will be free to travel only onehalf the distance that is traveled by the piston S in raising the article supporting bracket to any predetermined extent.

To insure an even vertical movement of the bracket, I provide upper and lower guide pieces 4-0, 41, mounted on a tubular post 30, and each carrying a pair of rollers 42 which engage the post 33 on opposite sides thereof, thus causing the tubular: post 30 to remain exact-lyparallel with the post during the vertical movement of the bracket. In further carrying out this same purpose, and to prevent any wabbling or vibration of the bracket as it is raised or lowered, I provide a support for the outer end of the horizontal arm 31 which is arranged in the following manner :-A flexible connection 43 -is attached to the outer end of the horizontal arm 31. It then passes over the pulley 44 conveniently mounted in a suitable upper support 45 directly over the end of the arm 31; thence over the double pulley 36; thence around the pulley 46, mounted in the horizontal lug 47 near the lower end of the post 33; and is then attached to the lower guide piece 41. This flexible connection 43 is drawn taut with the arm 31 exactly at right angles to the tubular post 30, and serves admirably as a support for the arm 31 to prevent any trembling thereof in its vertical movements, which tremors might be imparted to the article supported from said bracket during the dipping operation and thus mar the coating received by the article. The article holder 48 is removably secured to the arm 31 by the catch 49, and steadied in this position by the props 50.

In operation, presupposing the bracket to be in its lowered position indicated in full lines in Fig. 1, fluid is admitted through the inlet pipe 10 and thence through the branch inlet pipes 14 and 26 to the cylinders 4 and 22 respectively; and, at the same time, motive fluid is allowed to escap'erfrom the cylinder 4 through thepipes 16, and 15, but the outlet pipe 28 from the cylinder 22 is kept closed. The fluid entering the cylinder 4 will raise the piston 8 therein and the article supporting bracket will be raised along with it. The motive fluid entering the'cylinder 22 will depress the piston 24 and thus assist in raising the article supporting bracket by reason of the fact that the lpistons 24 and 8 are interconnected by the flexible connection 37 which passes over the fixed pulley 36 at a point between its points ct engagement with the pistons 9 and 24. hen it is desired to lower the article bracket, the motive fluid is allowed to escape from the cylinder 4 through the pipes 18 and 15 and from the cylinder 22 through the pipe while motive fluid is allowed to enter the cylinder 4 through the pipes 10 and 13. It will thus be seen that the fluid actuated. device, comprising, in general, the cylinder 22 and piston '24, operates actively only in raising the bracket, while the other fluid actuated device operates actively both in raising an d lowering the bracket;

By utilizing a plurality of fluid actuated devices, I am enabled to raise the bracket and articles of considerable weight secured thereto, 3y means of the mere gravitational force of liquid flowing from a relatively elevated source, without the aid of force pumps. Moreover, the novel manner in which the fluid actuated devices are interconnected insures an absolutely even speed of movement of the bracket as is raised and lowered, and further assists the steadying devices, heretofore described, in preventing any wabbling or trembling ot the bracket, as it is raised or lowered. The fact that the fluid inlet pipes 26 and 14 are in communication with each other insures an even pressure in both cylinders as the article holding bracket is being raised. 7

It is obvious that various changes may be resorted to in the form, construction and arrangement of the different parts of this machine without departing from the spirit a tank, an article supporting bracket, a fiexi= ble steadying device engaging both ends of the bracket, and a plurality of raising and lowering devices for said bracket. 7 I
